* More formats recognition for "Clear Screen" step. Improved the ability handling the alpha channel (% color translucency).
* Related to CPUID detecting:
	- Added support displaying correct SysInfo for recent multicore Intel CPUs x86-64 with HT/SMT (Core i3/i5/i7 and Xeon) based on Nehalem architecture.

+ minor and passive changes.
